FF6LE Rogue CE / Zone Doctor CE

I've uploaded Zone Doctor CE 0.2.1. This version fix the exit tags, the editor crash when last ROM used is not found and name correctly the default XML file path on first editor use (application directory path + "\settings.xml").

From now on there will be a single executable good for both 32-bit and 64-bit OS. I've also lowered the target Framework from 4.6.1 to 4.0 because the code really didn't needed 4.6.1. FF6LE Rogue CE target Framework is also 4.0.
